Title: Thermal transfer printer
Inventor: TAKANASHI RYOYU
IPC: B41J2/32
Filed: 1986-11-04
Abstract: PURPOSE:To protect a thermal head from breakdown, by detecting movement of a clamp on the circumferential face of a platen roller to the position of a thermal head through a clamp movement detector and preventing provision of a pressurizing signal, based on said signal, to a pressurizing mechanism by means of a pressurizing signal stopping means based. CONSTITUTION:When a clamp 10a of a platen 10 is positioned below a thermal head 13, a head protection slit 16 arranged on a disc 15 moves to the position of a slit detector 17 and a signal S is outputted from the detector 17. Upon receipt of the detected signal S, a slit decision means 18 judges that a slit is detected and counts pulses P through a count section 12. Since the width of the slit 16 is large, in this case, the count N is larger than a setting value (n). Consequently, the decision means 18 judges that said slit is a protection slit 16 and outputs an L control signal to an AND gate 19. As a result, a pressurizing signal Sp is not fed to a pressurizing mechanism 14 and the thermal head 13 is not pressed against the clamp 10a.

Abstract: PURPOSE:To enable a basic lateral oscillation of a laser device of this design at a low threshold value by a method wherein a stripe-like multilayer thin film composed of two negative conductivity type semiconductor layers which sandwich an active layer between them is provided, where a thin film section of the conductivity type opposite to that of the multilayer thin film is provided adjacently to at least one of the sides of the multilayer thin film. CONSTITUTION:Carriers are not only directly injected into an active layer 3 from a p-type region 8 but also through an n-type clad layer 2, so that an active region is small in series resistance and the oscillation is made to start with a low threshold current. A heat release is made to decrease in an optical output and light emitting efficiency hardly happens. Zn is made to diffuse in the p-type region 8 and a quantum well layer is made to turn into a mixed crystal structure due to the disorder of Zn, so that the active layer of a stripe W in width is made to be an optical waveguide and oscillated laser rays are trapped in the active layer. Furthmore, a paired electrodes 6 and 7 can be formed on the same plane owing to the p-type region 8, therefore the laser device of this design is made to be a planar structure and can be easily integrated together with other electronic circuit elements.

Title: Manufacture of high mn steel by refining
Inventor: KOROGI SHOHEI
IPC: C21C5/28
Filed: 1987-10-16
Abstract: PURPOSE:To stably and efficiently manufacture high Mn steel by refining in a high yield of Mn by charging Mn ore into dephosphorized molten pig iron before refining by blowing or in the first half of the refining and by refining the pig iron by blowing while keeping slag at a specified basicity. CONSTITUTION:Mn ore is charged into dephosphorized molten pig iron and the pig iron is refined by blowing in a converter. At this time, the Mn ore is charged before the refining or in the first half of the refining in which 60% of the total refining time does not elapse. During the refining, slag is kept at 1.0-4.5 basicity. The melting of the Mn ore is facilitated by the prolonged melting time and the desired yield of Mn is attained in the refining period. Since slag is kept at 1.0-4.5 basicity, the distribution of Mn in the molten pig iron is facilitated to increase the yield of Mn.

Abstract: PROBLEM TO BE SOLVED: To minimize noise magnetic field by providing a short coil, together with a deflection coil to an annular core. SOLUTION: In a uniaxial direction deflector, a deflection coil 2 is wound to the same number of windings between an upper coil and a lower coil and to change winding direction between the coils, so as to be reverse in the direction of generated magnetic flux 5. A short coil 7 is wound around an annular core 3 to link to the generated magnetic flux 5, and alternating current nozzle magnetic flux caused by a noise current component flowing through the deflection coil 2 is interrupted to stabilize deflected magnetic field 6 between a gap PQ and minimize harmful electron beam disorder. In an XY axis deflector, the deflection coil is wound in basically similarly the same as with to the uniaxial direction deflector.  Deflection current 4 from a variable current source 1 generates X-axis magnetic flux 6-2 of the same magnitude in the upper and lower deflection coils and in reverse direction to each other. A stable X-axis deflected magnetic field 6-1 is thereby generated between the gap PQ, and likewise for the case of Y-axis.
